Is there a reason why calling %ExecDirect() (or %Execute) won't set the %SQLCODE of the result set to 100 even when the query returns no data?

Here is the code in question with a bit of contrivance to force the issue:

set statement = ##class(%SQL.Statement).%New()
set result = ##class(%SQL.Statement).%ExecDirect(statement,"select top 0 0 from Example.Testing")
w result.%SQLCODE

The %SQLCODE is set to 0 in this case. The same happens if I use %Prepare and %Execute, e.g.

Hi folks!

Those who actively use unittests with ObjectScript know that they are methods of instance but not classmethods.

Sometimes this is not very convenient. What I do now if I face that some test method fails I COPY(!) this method somewhere else as classmethod and run/debug it.

Is there a handy way to call the particular unittest method in terminal? And what is more important, a handy way to debug the test method?

Why do we have unittest methods as instance methods?

How to write SELECT ... FOR UPDATE

InterSystems FAQ rubric

Since SELECT ... FOR UPDATE is implemented in many RDBMS as a method of explicit row lock acquisition, I think there are many cases where this function is used.

This syntax is not an error for InterSystems products, but it does not acquire row locks as expected.

This article will show you how to achieve equivalent functionality.

Using the Config.Configuration class and SYS.Database class methods, you can create and register a namespace database from the terminal.

Below is a series of execution examples that create database file /CacheDB/AAA/cache.dat and register database AAA and namespace AAA in the configuration file (cache.cpf).
* Execute in the %SYS namespace. *

* Make sure that this script runs as the user that is used for all IRIS processes to ensure that the directory has appropriate ownership and permissions *

Hi Guys,

I'm using the below code to download, extract files in a file directory then save data into a global, and remove the file directory as not needed anymore, but the issue is that the class(%File).RemoveDirectoryTree is not deleting, also tried class(%File).RemoveDirectory and same thing.

I have the following method call (have included html and css as well). when I debug the code in a browser, JavaScript seems to work fine. Loading image is coming up, table is getting hidden. But when I close the debug and just load the page and run it, loading image is not coming up, neither the table is hidden. Not sure what is going on? I need help to understand what I am doing wrong?

Recently I needed to restore a version of a production class, which was overwritten by compilation and running UpdateProduction. As the correct version was unavailable in the source control, I used journals to restore the data. Journals store a plethora of information about what's happening in the system and are quite a powerful tool. This article explains how to work with journals to extract the data you require.

Hi Guys, I'm resending this because I sent on the weekend and looks like it has not been noticed much

I'm not that familiar in using Javascript in Zen pages, so basically we have a priting utility (app) that requires us to add a bit of JavaScript call to facilitate printing from our Zen pages as below:

So I added XData link pasted the required script, is this the correct way?

As a former JAVA developer it has always been a challenge to decide which database was the most suitable for the project we were going to develop, one of the main criteria I used was their performance, as well as their HA configuration capabilities ( high availability). Well, now is the time to put IRIS to the test with respect to some of the most commonly used databases, so I've decided to create a small Java project based on SpringBoot that connects via JDBC with a MySQL database, another of PostgreSQL and finally with IRIS.

Ran into an issue with our upgrade from HealthShare Health Connect 2018.1.3 to IRIS HealthShare Health Connect 2022.1, that I thought I would reach out about, I already have a ticket open with WRC and started a chat on Discord. We have a couple of MS SQL tables that I have setup as Linked Tables within Cache to query NPI, Patient Account Information, Visit information, etc... When we upgraded last week we found that within a day or even a half a day that we were having problems with our JDBC connections.

I need to mount a database from another system. We have copied a device from another systems and mounted the device. I want to mount the cache database on this new device to our current instance of cache. If I add the name and path of this new device to the cpf file, the instance fails to start stating the database does not exist. If I attempt to create the database via the management portal, the new device is not accessible. I am missing something but I am not sure what it is. What do I need to do to make the imported device accessible by my cache instance?
